scaled version: buddy or banded pullups
progress to lighter band every/every other set
Body-weight pullups alone can be challenging enough but add weight to them, either with a weight plate or kb on a dipping belt, a dumbbell between your feet or by wearing a weighted vest, and you’ve got an extremely effective exercise for building muscle mass and increasing strength.
100 dumbbell thrusters for time (45/25#)
at the top of each minute, perform 3 burpees!
